A cinematic industrial platform for NEGBUY — connecting critical equipment, energy systems and technology across demanding industries.
A single, continuous build line. Scroll to walk the shop floor: casings are machined, modules are stacked to drawing, the rotor is balanced, and every unit is proven at full speed before it ships.
Casing halves go on 5-axis centres and the rotor discs are finish-turned to drawing. Every bore, face and rabbet is measured against the build sheet before the part leaves the cell.
Rotor blade rows and variable stator vanes are stacked and set to axial clearance. This is where up to 800 kg/s of air begins its rise toward an 18:1 pressure ratio.
Fuel nozzles and the thermal-barrier-coated liner are fitted into the casing. The flame sits near 1,400 °C while the casing wall is held inside its design limit.
Nozzle guide vanes and the hot-gas-path blade set go in with matched, traceable serials. These cooled aerofoils turn the hot gas into useful shaft power.
The stacked rotor spools up on the balancing bed. Probes read the shake in two planes and correction weight is trimmed until residual unbalance is inside spec.
A full-speed no-load run with every gauge logged against the build sheet. On sign-off the unit is preserved, crated and released with its as-built certificate pack.
An engineering cutaway of the machine we build and service — ten sub-assemblies, OEM-matched and fully traceable. Select a part to see its duty, material and availability, then build a live RFQ.

Every unit is built, balanced and run before it ships. Watch how the hot section comes together — then tell us which parts you need and we'll quote them against your build sheet.
We supply and overhaul equipment from the world's leading turbine OEMs — backed by certified quality systems and full traceability from feedstock to dispatch.
Real workshop, real hands. Scroll to move through the NEGBUY build-and-overhaul line — from heavy assembly to first fire.
01Rotors, casings and skids married up under overhead cranes — torque logged fastener by fastener.
02WPS-qualified welders, certified procedures and dye-penetrant checks on every critical seam.
03Blade sets fitted, clearances measured, then the rotor spun for dynamic balance.
04Speed, vibration and exhaust temperature watched live through first-fire and full-load.
05Coating, re-blading and liner refurbishment bring worn hot-gas-path parts back to spec.
Scroll — the rotor spools up, oil starts flowing and the core heats to full power. A live cutaway of what NEGBUY supplies and services.
Giant inlet guides pull 800kg of air per second into the compressor. Rotor spools up, inlet vanes adjust angle live.
Lube-oil skids push ISO VG-46 oil at 8 bar through bearings. Watch the amber oil line pulse — cooling + lubrication in one loop.
Compressed air meets fuel. 1,400°C flame held inside the liner while the casing stays cool — the hottest controlled fire in industry.
Exhaust expands through power turbine stages. Shaft torque becomes megawatts feeding the grid, ships and plants.
TW — 01Hot-gas-path inspection, blade replacement and balancing under ISO clean-room discipline.
TW — 02Pumps, coolers, filters and accumulators — complete oil circulation packages for turbines.
TW — 03Propulsion turbines, gearboxes and control retrofits for vessels and offshore platforms.
TW — 04Spares, commissioning and lifetime extension for generation and solar-hybrid sites.
One engine on the cradle, four trades around it, the hoist overhead. Drag the model to orbit the hall, or pick a station and the camera walks down the line with you.
Fitters seat the rotor, torque the case bolts and spin-check the shaft by hand — every value logged against the build sheet.
The welder fires in pulses up the step ladder while the QC lead scans every seam against the drawing. Lamp stays green — pass, pass, pass.
Lube-oil rigs fill, pressurise and leak-test each turbine at 8.2 bar. The amber floor line breathes with the test cycle.
The hoist lifts each finished turbine off its cradle into crates — stencilled, barcoded, sealed for the next plant on the route.

NEGBUY serves energy, turbine, oil & gas, marine, electrical, automation, EV and solar requirements.
NEGBUY identified a discontinued hot-section part from a photo alone and had a matched replacement on site within a week. The unit never missed its dispatch window.
The spares programme removed a huge amount of risk from our maintenance planning. Genuine parts, correct paperwork, and dispatch we can actually rely on.
Planned overhauls across three ports, delivered on schedule with full OEM documentation. That kind of coordination is rare in marine supply.
What we see on real units: fouling trends, outage sequencing, oil-sample verdicts and the paperwork that decides whether a machine returns on date.
MaintenanceA 2% heat-rate drift on a 200 MW frame is roughly 1.4 million dollars of fuel a year. Most of it starts as a thin film on the first three compressor stages.

OverhaulsThe HGP itself is a two-week job. The other ten weeks are drawings, serial numbers, inspection findings and shipping — and that is where outages actually overrun.
Read articleInspectionAn unplanned teardown costs weeks of production. A borescope costs a shift. The decision is about what you expect to find, not about how the machine is running.
Read articleStill unsure about something? Our engineers answer in plain language — no obligation, no pressure.
Both. We supply genuine OEM parts with full traceability, and where lead times or budgets demand it, form-fit-function equivalents built to the same specification. Every option is quoted with its documentation and warranty stated up front.
Send a part number, a nameplate photo or just the fault description. Our desk identifies the unit and returns a scoped, fixed quote — typically within 24 hours. Emergency stock dispatches from our global feedstock, often inside 48 hours.
Frame and aeroderivative gas turbines, steam turbines and generators across GE Vernova, Siemens Energy, Mitsubishi Power, Solar Turbines, Ansaldo, MAN and others — plus custom parts sourced and machined to your build sheet.
Yes. Beyond spares we run planned overhauls, hot-section repairs, balance work and commissioning support with certified crews, either at our workshop or on your site.
Parts ship with material certificates, dimensional inspection records and a standard 12-month warranty, backed by ISO 9001 quality processes and full traceability from feedstock to dispatch.
We do. We build dedicated consumable and capital-spares inventories for plants and fleets, so critical items are reserved against your name and released on call. You only pay for what you draw.
Tell us what's down, what's worn or what's due — we'll come back with a scoped fixed quote and a real dispatch date.
